BURGLAR-ALARM.

SPECIFICATION forming part of Letters Patent No. 337,995, dated Idaroh 16,1886.

Application filed December lfi, 1885.

To all w/wm it may concern:

Be it known that I,-'ALMER LEE SABIN, a citizen of the United States, residing at Washington, in the county of Daviess and State of Indiana, have invented a new and useful Burglar-Alarm, of which the following is a specification.

My invention relates to mechanical burglaralarms, and particularly to that class of such alarms in which separate cords or wires connect with and run from each door or window to be protected to a dog or detent which holds out of action the hammer of an alarm-bell.

The improvements consist in a hoop or ring for the attachment of the cords or wires, adapted to separate and hold the same apart, so that they may not become entangled; in an indicater consisting of a bent wire attached to each of the cords or main wires, adapted to enter a hole marked by a number, letter, or other character, and to be withdrawn from and prevented. from reentering such hole when the cord or wire to which it is attached is pulled to sound the alarm, and in a clasp or fastening for attaching the cords to doors, windows, &c.

Figure l is a perspective view showing my improved apparatus set ready for use; Fig. 2, a similar view showing the alarm tripped and set in motion by the pulling of one of the cords, and illustrating the manner of indicating the point from which the alarm is given; Fig. 3, a View of one of the indicator-pins; Fig. 4, a view showing the clasp referred to.

Various mechanical alarms have heretofore been patented, and in many cases they have been furnished with indicators for showing the source of the alarm; but such devices have usually been more complicated and costly in construction than is desirable, and the purpose of this invention is to Simplify and cheapen the construction,.while at the same time producing a thoroughly efiicient apparatus.

To this end I construct the alarm as follows: A indicates an ordinary clock-alarm mechanism, comprising a spring and train of wheels, an escapement, a hell or gong, B, and a bell hammer or striker, 0, all of which parts are common and well understood. The bell-hammer is provided with an arm, D, by which it may be drawn back and held out of action, l

which is likewise a common feature of construction. This alarm I place upon a wall, or, preferably, within a neat case, E, which may be secured to the wall or any convenient support. For convenience of illustration, 1 have shown and shall describe the alarm as thus incased; but it is to be understood that in lieu of the case any board or other suitable body may be made use of.

l indicates the back wall of the box to which the alarm mechanism A is secured, and G the side wall thereof, to which is attached the do tent H, which is preferably made in the form of a coiled spring, a, with a wire hoop, b, at its end, w hieh hoop is coiled to produce a ring, 0, and a series of loops or eyes, (I. These eyes serve for the attachment of cords or wires l, which pass thence through holes 6 in the case E, or in a board or other body, each wire or cord passing through a separate hole, the loops serving to separate and hold the cords or wires apart within the case, and the holes separating them when they leave the case.

From the case the cords or wires are lead through eyes, staples, or guides f in any required direction to the doors or windows to be guarded, to which they are attached in such manner that the movement of any one shall pull upon the particular cord attached to it and raise the ring 0 off the arm D of the bell-hammer, thus freeing said hammer and permitting it to be operated by the train to sound the alarm.

Each hole 0 is lettered, numbered, or otherwise marked to indicate to what point the cord or wire going through it passes, and each cord or wire is furnished with awire peg or pin, J, formed with a loop or eye at one end to receive a thread or cord, by which itis attached to the cord or wire I. These pegs or pins J are inserted with the cords or wires 1 into the holes 6, and pressed in until stopped by the loop or eye at their upper ends, and remain therein so long as the detent H is drawn down and remains hooked over the arm D of thebell-hammer; but if any one of the cords or wires I be drawn upward, as it will be by the movement of the door or window with which it is connected, the peg or pin J will be withdrawn from the hole through which that particular cord or wire passes, and all the others willremain in place. In this way and by simply looking at the mark oppositethat holeit can be at once ascertained what door or window has been opened and whence the alarm sounded.

To prevent the peg or pin J from again dropping into the hole from which it has been withdrawn, I bend each one as shown in Fig. 3, thus causing the end to swing off to one side as the cord or wire is slackened and permitted to fall back.

It is desirable to provide some cheap and ready means of connecting the cords or wires with and disconnecting them from the doors or windows in order that they may be quickly attached at night and detached in the morning. For this purpose I furnish each wire or cord with a clasp, K, which may consist merely of a piece of spring metal doubled or bent upon itself at the middle, and encircled by a ring, L, to compress the clasp and force its free ends toward each other.

Each door or window is furnished with a lug, M, to which the clasp may be applied, the arms of the clasp being passed on opposite sides of the lug and drawn firmly to the same by sliding the ring toward the lug. This device not only permits quick attachment and detachment, but its hold. while sufficient to insure the withdrawal of the detent from the alarm, is not sufficient to cause breakage of the cords or wires, the clasp slipping offthelug whenever the strain becomes too great, but not until the detent has been retracted.

The elastic detent, which may be made of rubber, or in any one of a variety of forms, withdraws out of the range of vibration of the arm D, and hence cannot interfere with the movement thereof.

Having thus described my invention, what I claim is 1. In combination with an alarm mechanism provided with an arm, D, a detent, H, consisting of a coiled-wire spring, having ring a to engage over said arm.

2. In combination with alarmAand its arm D, detent H, having hoop or ring c, and eyes (1, for the attachment and separation of cords or wires I.

3. In combination with an alarm mechanism, a detent for holding said mechanism out of operation, a series of wires or cordsattached to said detent, guides or holes for said cords, each marked to indicate the point to which its wire or cordpasses, and pins or pegs attached to said cords and serving-to indicate by their.

withdrawal the source of the'alarm.

4. In combination with an alarm, a detent therefor, a series of cords or wires attached to said detent and to different doors and windows, a series of guide-holes for the cords or wires, each hole marked to indicate the point to which its cord or wire proceeds, and bent pegs or pins attached to the cords and inserted beside the same in the guide-holes, said cords serving by their withdrawal to indicate which wire is pulled, and being prevented by their bent form from re-entering the holes.

7 5. In combination with the operating cords or wires of an alarm, as described, and with lugsproject-ing from the doors and windows to be protected, clasps K, attached to said cords and provided with rings L, substantially as and for the purpose set forth.
